This G-SHOCK was crafted for those unique secret missions that demand accuracy and stealth. The countdown timer function has a large, easily identifiable button for direct access and sure operation under the hardest of conditions. At the end of a countdown, informs are issued by either a vibration or a tone plus LED flash operation. The large face is configured to make sure that the countdown timer is easily seen in the dark. A high luminance LED can be configured to illuminate for one, 3, or five seconds, and a Car Light function triggers the face to brighten whenever the watch is tilted towards the face for reading. The unique shock absorber style of the back of the watch helps to make sure that vibrations are felt when it is used. Grey resin band digital with neutral face.
